Anyone used stans or other tubeless alternatives during cold weather? I was thinking that maybe the sealant was getting stiffer at low temperatures and therby start leaking
I am about to order stans rims and am thankful for any input.

Worked great for me for my first three rides until I got ambitious and decided to lower the pressure to 25 psi. I weigh 175, and was pumping the tires up in a 50 degree garage before taking them out in 15-20 degree snow (so the effective psi would be somewhat lower), so this was probably a bit much. At that point some snow got into the bead and broke the seal, making my rear go flat and my front leak slowly. I know it was the snow because I had been riding them previously in cold conditions (0-20 degrees) but without a lot of unpacked snow, and once they were back in the garage I could get them to re-seal after the snow had melted. We're getting more snow tonight, so I'll take them out again at 30 psi and make sure they can handle the snow at that pressure. At any rate I think the only issue is snow getting pushed into the bead and breaking the seal at very low psi, I don't think "normal" (ie above zero) temperatures effect the sealant much, if at all. I'm thinking that tubes may be a necessity for extremely low air pressure (because of the snow intrusion problem), but you really can't go wrong the Stan's rims- super light, nice width, mounting a tire tubeless is a snap, and they seem to be holding up well.

Have ridden hundreds of miles on snow packed roads in temps as low as -5f, without any problems. I use the wire beaded Nano. Would recommend 32psi rear 30psi front. I weigh 170.

-I thank you very much for the useful information. I live in San Diego/Del Mar right now but I will bring back my bike to cold Sweden next year and were therefor wondering about its performance in at low temperatures.
-Would you say that once set up properly, stans rims plus sealant needs as little or less attention as traditional tube/tire/rim combinations all year round?

Make sure you never let the sealant dry up. Every few months take the wheels off and shake them. If you can no longer hear the sealant sloshing around in there, deflate the tire. Gap the tire bead and rim strip just enough to add more sealant. I add more sealant 2-3 times during a tire's life, before it wears out.
I just check my sealant level after 2 months...had to replace a spoke nipple
Some the latex had formed a ball about the size of a larger marble. Just curious if this has happened to anyone else. I removed the ball, added a bit more sealant and went on.

That's completely normal. The ball of crystaline had originally formed to a leak somewhere in the system and had broken off after the seal was formed and the tire kicked up some RPM's. Be sure to shake up sealant before adding more in this case. Usually, when I top off my wheels, I do not shake and add only the top of the solution with more of the laytex and less of the crystaline. This has worked for me quite well for the past two years.
